SUMMARYHeterotopic tendon mineralization (ossification or calcification), which may be a feature of tendinopathy or which may develop following surgical trauma (repair or graft harvest), has not received much attention. The purpose of this article is to review the prevalence, mechanisms and consequences of heterotopic tendon mineralization and to identify the gaps in our current understanding. We focus on endochondral heterotopic ossification and draw on knowledge of the mechanisms of this process in other tissues and conditions. Finally, we introduce a novel murine Achilles tendon needle injury model, which will enable us to further study the mechanisms and biomechanical consequences of tendon mineralization.

“…Auricular calcification has also been described in setting of several other endocrinopathies like diabetes mellitus, hypothyroidism and acromegaly. It has also been associated with systemic diseases like cold hypersensitivity, alkaptonuria, hypertension, scleroderma and rare conditions like systemic chondromalacia 30 31. Clinicians should be well aware of this rare manifestation and its association with endocrinopathies and systemic diseases.…”

Petrified pinna refers to the calcification or ossification of the external auricular cartilage. It is an uncommon clinical entity and is most often associated with local trauma, frostbite or inflammation. Auricular calcification may be the exclusive cutaneous marker of underlying endocrinopathy. It has been most commonly associated with adrenal insufficiency and other endocrine conditions like diabetes mellitus, hypothyroidism and acromegaly. We present a 47-year-old Caucasian manwho presented with acute pericarditis with tamponade physiology, who was found to have petrified pinnae as a telltale sign of the underlying autoimmune polyendocrine syndrome type 2.

“Petrified ears” or calcification of auricular cartilage is an uncommonly reported condition. The most common causes of this phenomenon are local trauma, frost bite, and inflammation. Adrenal insufficiency is the most frequent systemic disease associated with auricular calcification. We present a case of idiopathic adult-onset pituitary insufficiency with hypocortisolism and bilateral auricular calcification. Recognition of the association between auricular calcification and adrenal insufficiency can be an important step toward the identification of a life-threatening cortisol deficiency.
